XSLT is an interesting case.  While the unqualified elements in some
sense "belong" to the surrounding qualified XSLT markup, they clearly
aren't treated as properties of the XSLT markup.  I'd strongly not
recommend using my filters on XSLT templates, and I'll add some
documentation to that effect.  (Exclusions make that easy to achieve
even in mixed contexts.)

Was that in the original XSLT plans?  Or did that emerge as namespaces
developed and had to be encapsulated in XPath?  I can't remember.

XPath in XPointer with xmlns - now there's a demonstration of how much
fun QNames can be.
